Last updated: April 2026 dataVitamins not elsewhere specified — including Vitamin D (calciferol and cholecalciferol), Vitamin K (phylloquinone and menaquinone), and Vitamin H (biotin, when classified separately) — are grouped here when no more specific SITC heading applies. Vitamin D3 (cholecalciferol) is commercially significant as a pharmaceutical API and dietary supplement ingredient, with lanolin-derived supply chains linking it to wool-processing industries. FDA entry review applies to human-use grades, and the "NES" designation means classification officers may require detailed chemical identity documentation to confirm that a more specific heading does not apply. Importers should provide IUPAC names, CAS numbers, and certificates of analysis to support both classification and admissibility.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Importers should provide the chemical's IUPAC name, CAS registry number, and a certificate of analysis confirming identity and purity. Customs authorities use these to verify that the substance does not fall under a named vitamin heading (A, B, C, or E). A licensed customs broker familiar with chemical classification can help prepare a binding ruling request if the classification is genuinely ambiguous.
Most commercial Vitamin D3 (cholecalciferol) is produced from 7-dehydrocholesterol extracted from lanolin, a byproduct of wool scouring. This ties D3 supply to the global wool industry and a relatively small number of specialized chemical processors. Supply disruptions in wool processing or lanolin refining can create lead-time challenges for dietary supplement and pharmaceutical manufacturers relying on this input.
